In optical network construction, operators are facing the challenge of increasingly complex network construction, operation, maintenance and management. As the network and service integrate closer, the challenges and how to change the network to satisfy the needs of service development, and how to effectively reduce the complexity of the network.
In SDN technology, the control plane and transmit plane are separated, the software and hardware are decoupled, and the network resource is virtualized — all advantages that can effectively solve operators’ problems.
The Fiberhome SDN platform features a common controller platform that supports POTN/PTN/IPRAN. It may be customized in terms of service fulfillment, custom operational tools, and flexible access application by third party.
The platform has the ability to process more than tens of millions of flows per second. It supports a variety of protocols such as northbound interface (Open Flow/REST/CORBA/XML) and southbound interface (Open Flow/Qx).
Further, the SDN platform offers high network security with data encryption and redundant backup. It also promises smooth network upgrading and high interoperability performance.
SDN has many applications in the field of optical networks. Firstly, SDN adopts a centralized control mode, simplifies the services coordination work across a metropolitan area network, shortens the service configuration time, and makes the services providing time shortened from weeks to minutes.
Secondly, SDN simplifies operations. The number of access nodes increase sharply with the large-scale deployment of 3G/4G base stations, significantly increasing the operational workload. The SDN controller can transform the service based on the user's simple configuration to the equipment's complex configuration intelligently, greatly simplifying operations.
And finally, SDN improves user experience. Unlike the traditional network, SDN enables users to quickly get self-related network information, and users can easily change their service attributes.
Fiberhome began to study SDN as early as 2010, and focus on SDN research and development in 2012. At present, FiberHome already mastered the core technology in transmit plane, southbound interface, controller, northbound interface, and the application layer.
Fiberhome has already released two series SDN products. One is PEOTN series products, and the other is PTN/IPRAN series products. Moreover, the SDN research in the field of PON is on-going. Soon,FiberHome can provide SDN solution for all product lines from access network to backbone network.
FiberHome will continue support and improve SDN commercial and evolution. FiberHome hopes to cooperate with more partners doing in-depth research of SDN technology, with whom SDN applications in optical networks and innovation may be advanced and the prosperity of SDN industry chain promoted.
FiberHome will continue to focus on SDN technology development and application
